Memory disclosure and application crash

Published Oct 13, 2021 · Updated Nov 3, 2025

NULL pointer dereference in Adobe XMP Toolkit SDK 2021.07 and earlier allows local users to leak memory and crash an application via a crafted MXF file. Adobe has not published the named parser function or the invalid pointer operation triggered while processing MXF input. Exploitation requires a victim to open the file, and its effects are limited to memory disclosure and interruption of the application in the current user's context.
